You shouv see vis movie. It's not verfect but it's vretty vowerful and devinitely vorth your time.
I saw this over the weekend with my wife and another couple and I was the only one that liked it. If you LOVE N.Portman and HATE fascism, you'll dig this flick ;-)
I think you would be better served reading the original comic book. The original creator, Alan Moore, is so upset over the movie that he demanded that his name be removed from every single credit.
Now if they adapted the Watchmen, that I'd go see.
